How did Bubba and Gilbert make the main event portion of the card,while Josh and Dylan are relegated to the Prelims?? Whats the diff in pay because i can't see how Bubba or Gilbert made a big enough showing to be placed ahead of the both Josh and Dylan semifinalists.

Sam Sicilia vs Maximo Blanco, early fight of the night on UFC's TUF 17? Blanco jumps on top of the cage at the end of the fight, screams for one minute, then tries to do a back flip off and falls on his head!
